Yes, that’s exactly right. The amount is set in stone, as the mint has a different signing key for each amount. So only by verifying the signature the mint knows the amount is valid. And because the mint only signs notes that have been paid for, it can also trust that this token is actually spendable.
When the mint creates a new output, it doesn’t actually know what the output looks like. So when I use that output as an input it can only verify that it’s valid, nothing more
Because the mint never learns how the secret (which is the crucial spending condition of a regular token) looks like. The signature is blinded. It can not correlate a mint and the act of redeeming a token.

When I started my LN journey I posted a Lightning Meme on Reddit every day for a few months.
Maybe now is the time for #Cashu memes? 
Shill me some npubs to follow 💜

Super proud to have built one thing from that list 🔥🙌🏻
95% custodial zaps… wow! That’s why there is npub.cash 🥜🔥

What is the performance impact of verification vs. JSON parsing ?
Cashu Payment Requests are coming along great!

Who wants to chime in and get a POS device rolling?
Check out the API controllers and write some tests 🤙 https://github.com/cashubtc/npubcash-server
As long as your have a Blink account, yes. Blink is required as wrapper, as mints do not have WebSocket support yet.
Actually if you do I would really appreciate you testing it. If your are interested I’ll send you some “draft” instructions on setting it up
All green 💚 Is there anyone here that would like to contribute on some npub.cash API testing? 
That’s nuts 🔥🥜 nostr:note1xk7amvu8ar922y8j85jcfn2egpxkk7tjee2e6h0n65lhxq8a2fpspvhsxy
It is! One week of Mallorca before a month full of amazing ecash stuff 🙌🏻
Today was my last day of “charging up” for the journey ahead. This will last me quite some time. The things we are going to build are going to be amazing 🙌🏻
I can not wait to get started 🥜💜 
PV nostr 💜🤙
Working on a proper test suite for npub.cash. If this is going to result in sweet dreams or nightmares is unsure lmao… 
NIP07 is the browser extension spec. It lets you login to nostr apps using a browser extension like nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm
NIP46 is the remote signer spec and lets you login using a remote signer like nsec bunker or nsec.app
A permissionless Lightning Address for everyone, built on Cashu
and Cashu.me a state-of-the-art Cashu Wallet PWA
